[ Upstream commit 3415f6baaddb9b39d7112247ab39ef3c700f882e ]
There are many places in the driver where the return code from a
function call is captured but without a subsequent test of the
return code and appropriate action taken.
This patch adds the missing return code tests and action. In most
cases the action is an early exit from the calling function.
The function lan78xx_set_suspend() was also updated to make it
consistent with lan78xx_suspend().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
